How do we check the dog’s mental state?

The mental state of animals is controlled by the cerebral cortex. Healthy dogs show a normal mental state. They often react quickly to external stimuli with the movements of eyes, ears, tail, and limbs. When the dog’s a central nervous disorder, the dog will appear mentally excited or mentally inhibited.


1. Mental excitement:

Mental excitement is the result of central nervous system skill hyperactivity, light expression is commotion restlessness, panic, fear, severe by slight stimulation will produce a very strong reaction, regardless of obstruction to forward or back, even jump into the ditch, run wildly. Mental overexcitement sees in the brain disease, for example, meningeal congestion, cranial pressure rises to wait a moment, metabolization obstacle, poison is waited a moment like chemical drug or plant poison, infectious disease waited a moment like hydrophobic.

2. Mental depression:

Mental inhibition is a manifestation of the predominance of cortical inhibition processes, another form of central nervous dysfunction, with a low or absent response to stimulation. According to the degree, it can be divided into the following categories:


3. How to check?

It is abnormal for a dog to be too energetic or too dull.

(1) Depressed spirit: This is the least inhibited phenomenon of cerebral cortex activity. The affected dog is slow to respond to things around, stands idly, his head is low, his ears are bowed, his eyes are half-closed, and he does not listen to the call of his owner. But they still respond to mild stimuli.

(2) Lethargy: Moderate inhibition of the central nervous system. The affected dog is in an unnatural sleep state and is unusually slow to respond to external stimuli. It needs strong stimulation to produce a short response, but it will soon fall into a deep sleep again. It is commonly seen in encephalitis or elevated intracranial pressure.

(3) Coma: this is a highly inhibited phenomenon of cerebral cortex skills. The affected dog loses consciousness completely, has no response to external stimuli, and does not want to get up on the ground. The muscles of the whole body are relaxed, the reflex disappears, and even the pupils dilate and excrete incontinence. Keep only irregular breathing and heart pulse. It has no response to very strong stimulation and is commonly seen in patients with poor prognosis, intracranial lesions such as encephalitis, brain tumors, and metabolic brain diseases such as hypoxia, ischemia, hypoglycemia, dehydration, etc.
